Please note I'd recommend a local hub. Hubs can be had for under $50.
Borrow one first to make sure there are no connectivity issues -- in
large networks there can be.
The gateway solution you propose has a problem. DHCP will not function
across a gateway(router) without a relay on the gateway. You'll have to
support DHCP relay or use NAT on the gateway for the other two nodes to
get IP addresses.
DHCP works using broadcasts. Broadcasts normally stop a
routers/gateways.
